Alex at Marginal Revolution and the fellers at Fraters Libertas have some takes on the top 50 conservative-themed rock songs. Maybe I missed it, but why hasn't anybody mentioned "We're not Gonna Take It" by Twisted Sister?
we've Got The Right To Choose And
there Ain't No Way We'll Lose It
this Is Our Life, This Is Our Song
we'll Fight The Powers That Be Just
don't Pick Our Destiny 'cause
you Don't Know Us, You Don't Belong
Perhaps that's more libertarian than conservative.
